Using these extension methods, generating PNG images is straight-forward: using

Copy the appropriate QrCodeBitmapExtensions.cs file to your projectįor macOS, Linux, iOS, Android and multi-platform projects.

Add the NuGet dependencies to your project.

Select one of the imaging libraries below.

Therefore, ToBitmap() has been removed and three options are now offered in the form of method extensions. NET 6, System.Drawing is only supported on Windows operating system and thus cannot be used for multi-platform libraries like this one. Var qr = QrCode.EncodeSegments(segments,, 5, 5, 2, false) Var qr = QrCode.EncodeText('Hello, world!', ) įile.WriteAllText('hello-world-qr.svg', svg, Encoding.UTF8) Or by running a command in the Package Manager Console Browse / search for qrcodegenerator / Install NET Core > Console App (.NET Core))Įither via Project > Manage NuGet Packages. NET Core 3.1 (or higher) ( File > New > Project.

Computes optimal segment mode switching for text with mixed numeric/alphanumeric/general/kanji partsĬreate a new Visual Studio project for.

Encodes Japanese Unicode text in Kanji mode to save space compared to UTF-8 bytes.

You can create a list of data segments manually and add ECI segments.

You can specify an error correction level, or optionally allow the library to boost it if it doesn't increase the size (version).

You can specify the mask pattern manually, otherwise library will automatically evaluate all 8 masks and select the optimal one.

You can specify the minimum and maximum version number allowed, and the library will automatically choose the smallest version in the range that fits the data.

Example code for WinForms, WPF, ASP.NET, ImageSharp, SkiaSharp etc.

Open source code under the permissive MIT License.

Encodes numeric and special-alphanumeric text in less space than general text.

For raster bitmaps, additional code is provided.

Output formats: Raw modules/pixels of the QR symbol, SVG and XAML path.

Supports encoding all 40 versions (sizes) and all 4 error correction levels, as per the QR Code Model 2 standard.

Many more programming languages, and the Project Nayuki web site has additional information about the implementation. It is mostly a translation of project Nayuki's Java version of the QR code generator. NET Standard 2.0 and therefore runs on most modern. Open-source library for generating QR codes from text strings and byte arrays.
